IEC TS 62950:2017 PDF

Overview

IEC TS 62950:2017 provides a reference framework for specifying and testing smart capabilities and smart operating modes of household and similar electrical appliances, small scale energy supplies (SSESs) and other devices (collectively referred to as smart devices). The Technical Specification focuses on electricity consumption (though principles and architecture can be applied to other energy types) and does not set minimum performance requirements. Instead it defines terminology, logical architecture and measurement approaches to describe how devices respond to standard instructions and smart‑grid conditions.

Key topics

• Terminology and definitions for smart capabilities, smart operating modes, CEM (customer energy manager) and DEM (device energy manager).
• Reference framework and logical architecture showing CEM/DEM/device configurations and interactions (figures and tables in the TS).
• Classification of smart operating modes, including modes such as: constrain/reduce load, start/increase load, defer cycle, start/increase supply, and no supply - plus mechanisms for overrides and status indicators.
• Response rules and measurement approaches that describe how devices should react to standard instructions and how to measure those responses (timing, duration, fixed vs. floating reference values, exclusions).
• Testing principles and setups to determine compliance with smart‑performance claims and to evaluate the impact of smart operation on normal device performance.
• Information requirements for manufacturers: technical information for standards, user documentation and installer guidance related to smart functions, safety and protections.
• Safety, protections and user interaction considerations when devices operate under smart commands (to avoid energy waste or unsafe states).

Applications and who uses this standard

IEC TS 62950:2017 is practical for stakeholders involved in the design, testing and deployment of smart energy products:

• Appliance and device manufacturers - to define and document smart features and provide consistent claims about smart behavior.
• Test laboratories and certification bodies - to develop test procedures that measure smart operating modes and verify response characteristics.
• Utilities and aggregators - to specify how consumer devices respond to demand response and grid signals.
• Smart home/energy system integrators and CEM/DEM developers - to ensure interoperability and predictable responses in smart grid scenarios.
• Regulators and standards committees (IEC TC59) - to harmonize terminology and architecture across appliance performance and smart‑grid standards.

Related standards

IEC TS 62950:2017 complements appliance performance standards and broader smart‑grid standards developed within IEC (notably work by IEC TC59). It should be used alongside device‑specific performance standards and national requirements when specifying smart capabilities and testing procedures.
